IMPROVEMENT |N BASE-BURNING FIRE-PLACE HEATERS.

The Schedule referred to in these Letters Patent and making part of the same.

Toflall whom it may concern Be it known that I, JULIUS Janene, of Tompkinsville, in the county of Richmond and State of New York, have invented anew and useful Improvement in Fire-place Heaters; and I do hereby declare the following to be a full, clear, and exact description thereof, ,which will enable those skilled in the art to make and use the same, reference being bad to the accompanying drawing forming part of'this specification, in which drawing 1 Figure 1 represents a vertical section ofmy heater from front to rear.

Figure 2 is a plan or top view of the same.

Figure 3 is a vertical cross-section of the same, the line a: a', fig. 2, indicating the plane of section.

Figure 4 is a horizontal section of the same, the upper part of, said figure being bisected in the plane indicated by the line'z z, and the lower part in the plane indicated by the line 9 y, 1.

Similar letters indicate corresponding parts."

This invention relates to a fire-place heater the front or fire part of which is separated by a frame from the hind or air-heating part in such a manner that the front part can be readilyremoved without disturbing the rear part, and that easy access can be had to the interior of the heater for the purpose of clcaniugor repairing, said partition or frame being provided with "doors, which can be opened. after the front part of the heater has been removed.

()n the top of the front part is placed a water-urn, which communicates, by means of a pipe, with a vessel situated on the inner or rear part of the heater in such a manner that, by pouring water into the urn, the level of the water in the inner vessel can be observcd and controlled at all times without removing or disturbing any part of the heater. i

The heater is provided with a perforated reservoir for the fuel, and with a distributing cone, which is situated in the center of the grate and rocks with the same, so that the fuel on dropping down on said cone is uniformly distributed over the grate, and by shaking the grate the fuel is prevented from clogging up the reservoir-and the fire is readily cleaned;

In the back part of the heater is a damper, and if this damper is open the draught passes direct up through the smoke-pipe; but if said damper is closed thedraught passes down through lateral vertical flues into side fines forming the sides of the fire-place, and

thence down into the lower side fines which form the sides of the ash-pan, and which communicate, by means of a central upright fiue, with the smokestack, and as the hcatedgases are thus compelled to circulate round the entire stove a large body of air is heated to ahigh' temperature with great. economy in fuel.

The air-pipes are oval, so as to increase their heating surface as compared with the quantity of air passing through them, and they are placed in oblique positions toward each other, so-that the heated gases are compelled to impinge against their fiat sides, and the air passing up through said pipes is rapidly heated to a high tem ieratnre.

.In the drawing-the letter A designates thcbase of my heater, which is occupied by theash-pan B, the lower side fines G, and the central upright fine D, (best seen in the lower half of fig. 4,) access being had to the ash-pan through a door, I), to the lower side lines through doors 0, while a door, (Z, figs. 1 and 3, leads from thea'sh-pan in the central upright due.

The spaces between the lower side fines and the ash-pan conumrnicate,.by means of holes, 0, with the external air.

On the base Arests the middle part In of my heater, which is partly occupied by the grate F and they upper side fines G, while the spaces between the grate and said upper side fines communicate with the spaces below through holosf, (best seen in the upper half of fig. 4,) J

Access is bad to the upper side fines through doors g, and holes'h lead from these upper side fines down to the lower side fines, while they communicate through vertical back fines H with the next part above, as will be presently explained.

The grate F is circular in form and slightly concave, and it rests upon a pin, i, (see fig. 1,) which passes through the shank j of a cone, I, that is mounted on the rock-shaft 7;,thc grate being provided with a central hub, I, which embraces the shank of the cone so that said grate can be turned independent of the cone; but if a rocking motiouis imparted to the cone,

this motion is communicated to thegratc.

The upper part of my heater is composed of two parts,- J and K, and from the base-plate o of this part extends a circular flange, m in a downward direct-ion far enough to embrace the rim of the grate if the heater is in position. I

This circular flange, together with the grate, form the fire-place of my heater, and round the upper edge of said circular flange extends a perforated pipe, 11, which communicates with the external atmosphere, (see fig. 1,) so as to throw jets of air into the gases rising from the fire-place for the purpose of consum- -ing said gases.

From the base-plate o rises a vertical partition-platc, 1), which is intended to lie close against the wall of the chimney, and which separates the front part-J from the'back part K.

The front partJ is placed loosely upon the base-plate V 0, which is provided with a confining flange, serving to retain said front part in position.

In said front part is secured the fuel-reservoir r, to which access is-had through doors 3, and which is perforated with a large number of holes, (see fig. 1,) so that the gases evolved from .the fuel in the reservoir are free to escape in thecomhustion-chamber t, where the same are consumed, and all danger of an explosion is thereby avoided.

'lhe comlmstion-chamher t occupies the lower portion of the frontpart J and the whole of the back part K, and it communicates through aperture a with the central upright flue D, which con'nnunicates with the smoke-pipe M, (see fig. 1,) and ttn'ouglrlateral apertures r, with the back tlues H, (see 3.)

The aperture 16.6311 ,be opened or closed by means ot' a damper, '20.

Through the combustion-chamber extend the airflucs a, which are made oval (sec fig. 2) andplaced in oblique positions toward each other, so that the heated gases rising from the fire are compelled to impinge against the flat sides of said flues, and thereby the heating etfect is materially increased.

When the damper w is open the draught passes 'right up through the aperture 10 to the smoke-pipe,

but alter the tire in the heater is going said damper can be closed, and then the draught is compelled to pass from the combustion-chaniher through the latcral aperture 0 into the lateral hack tines H, thence through the upper side flues G and apertures it into the lower side jflues C, and through them and the central vertical fined) up to the smoke-pipe.

By causing the heated gases to circulate in this manner round the air-spaces e and f the air passing up through said air-spaces is heated before it reaches the air-fines a, and a greateconomyin tuel is effected.

The heated air emanating from the air-tines it passes up through the main air-flue N into the upper part of thebuildin".

In this main air-flue is situated a water-vessel, O,

which is designed to hold water for moistening the heated air, and communicates, by means of a pipe, I),

with a feed-cup, 1, plaeed-o1rthe top of thefrput part J, (see fig. 1.)

This feed-cup is situated at a level a little below the top of the vessel 0, so that if the feed-cup is filled up the water in the vessel 0 will not overflow.

13y observing the level of the water in the feed-cup a sutlicicut supply of water can always be kept in the vessel 0 withoutopening or removing the partitionplate p.- 7

1n the partition-plate 11 are doors, (1', which can be opened when the front part J of the heater has been removed, and thus ready access eanbe had to the main air-flue for the purpose of cleaning or repair-in".

The damper w is operated by a rod, c', extendiug through the partition-plate 11.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1, The combination of the feed-cup I, pipe b, and water-\essel O, substantially in the manner shown and described.

2. l.he'oval aiupipcs (1., arranged in the combustionchamhcr of a heater in oblique positions toward each other, as and for the purpose set forth.

3. The back fines H, upper side fines G, apertures 72, lower side flues O, and central back flue D, in combination with the combustion-chamher of a heater constructed and arranged substantially as described.

4. The doors (1" in the vertical partition 1), in combination with the front part J and back part K of'a tire-place heater construct-ed substantially as set forth.

5. The grate 1+, formed with huh I encircling the shank of the cone 1, in connection with the pin i passing through said shank, and with the rock-shat't K, on which the cone is mounted, substantially as and for the purpose described.

This specification signed by me this 3d day of June, 1870.
